Linear

Dynamic headphones are much more different than
most people realize. For the same sound pressure level the power needed
with different headphone models can vary up to a factor of about 500!
Impedances can be different to a factor of more than 20!

This is the reason why different headphone models have very individual
requirements to the headphone amplifier driving them in terms of voltage
and current. Everybody who once has connected a high quality headphone
to any given standard headphone output knows about this problem.

In my opinion, the Linear belongs to the reference class of its
kind. It creates a relaxed, open, neutral and detailed acoustic
image. – Studio Magazine

Since the launch of the Linear in 2004 there is a high end headphone
amplifier to realize even the highest demands to reference quality
headphone music reproduction. The selectable gain (0 dB, 10 dB, 20 dB)
of the Linear effectively optimizes the output level of the zero global
feedback Class A output stage. Practically all high quality dynamic
headphones available will show their best possible performance, no
matter if you have an easy to drive low impedance pair of headphones or
an ineffective pair of 600 ohms studio cans.

Top notch components and a highly sophisticated
circuit design

Carefully selected top notch components and a highly sophisticated
circuit design guarantee top performance listening pleasure. For stereo
setups with just one source like a CD player or a turntable with a phono
stage the Linear is the simplest and most effective active preamp one
can think of. All audio connectors including the two Neutrik phone jacks
come with gold plated connectors. No external Y-adapter is needed!

The faceplate and the massive milled aluminium knob for the smooth
running 27 mm ALPS high grade volume control are available in anodized
black or silver.

To get the best out of your headphone you will have to try the
Linear.
